This looks like a blob image problem:

Bug 1425484 may fix it.

[Milan Sreckovic [:milan] (needinfo for best results)]

Is it a blob image problem that I can't see the perf graph at all?  Separate bug?

Comment 3

[Jeff Muizelaar [:jrmuizel]]

That sounds like a separate bug.

Comment 4

[Jeff Muizelaar [:jrmuizel]]

It looks this page is mostly a big SVG

Comment 5

[Jeff Muizelaar [:jrmuizel]]

This runs mostly ok on Windows now.

This improved a lot with the blob recoordination work but it looks like it's still affected by the issue with container size changes invalidating their children.

Some information about the topic of the JPro-Team:
At the end of 2019 we've changed our rendering engine.
Previously we were mainly generating one big svg-element.
Now we are creating many div's with some small svg-element inside.
We've done the change to better allow embedding non-svg element,
because <foreignObject> was very unstable on all browsers.
This might be relevant for performance tests ...

Thanks for the update! It does seem to behave somewhat better now than what I remember but probably could still be improved in Firefox.

Seems to run well now - the worst case blob raster I see is 6ms. Will probably benefit from any general blob raster work we do though.
